Using Graphical Mods for Final Fantasy XIV on Linux: Steam vs XIVLauncher

[oniflix]

Introduction
I have installed Final Fantasy XIV via Steam, but I would like to use graphical mods, especially one that I'm particularly fond of. I'm looking for a way to make mods work on Linux (CachyOS), preferably through Steam alone, or alternatively with XIVLauncher.

Current Situation
I've tried using XIVLauncher, and it works, but I'm facing an issue. I can't select DLSS and FSR options, and the cause seems to be the default Wine version used.

Lack of Experience
I lack the experience to modify the Wine version used. For example, it would be helpful to have a tab similar to Steam's where we could choose a different system version that's installed, such as Proton-CachyOS or Proton-GE, which support FSR and DLSS since they work with Steam.

Image Quality Concerns
The image quality seems much better when launching through Steam.

Request for Solution
Is there a way to use graphical mods on Linux (CachyOS) for Final Fantasy XIV, either through Steam alone or with XIVLauncher, while maintaining the ability to use DLSS and FSR?
